"I'll Be Missing You" is a tribute song by American rapper Puff Daddy and singer Faith Evans, featuring the R&B group 112. It honors the Notorious B.I.G., a fellow artist on Bad Boy Records and Evans's husband, who was murdered on March 9, 1997. Released in May 1997 by Bad Boy and Arista Records as the second single from Puff Daddy's debut album, No Way Out (1997), the track incorporates a sample from the Police's 1983 track "Every Breath You Take," with an adapted chorus by Evans. Additionally, it includes elements from the 1929 hymn "I'll Fly Away" by Albert E. Brumley and features a spoken introduction layered over a choral arrangement of Samuel Barber's "Adagio for Strings." Its music video was directed by Hype Williams and filmed on sites in Chicago.
